  a promoter sequence

  a Kozak's consensus sequence

  a Shine Dalgarno sequence

  Half-n-half Clue
 

2.

If the mammalian genetic code were a four letter code, then it would have the potential to encode...

  256 amino acids

  64 amino acids

  216 amino acids

  128 amino acids

  Half-n-half Clue
 

3.

The enzyme that forms a peptide bond between adjacent amino acids in the ribosome during translation is called :

  Half-n-half Clue
 

4.

The process of translating mRNA into protein occurs...
